I was working on the OAuth Walkthrough: Test Authorization with a Web Server but encountered an error that I couldn’t solve for a week. When I try opening the link
http://localhost:8000/request_token.php as step 3.8 says, this error pops up:
I can’t understand what ‘vender/autoload.php’ is and what I should do to resolve this. Could someone please kindly help me out?
Have you downloaded composer and run
php composer.phar install?

However, when authorizing this page popped up:
Could you give me a hint again?
In the .env you’ll need to configure your client secrete that you get from your application in the OAuth section of the Developer Dashboard.
I can assure you that I copied my app’s secret to the .env file correctly.
